More elegant way then .Split(']');

Question

Dear All,

I have ListView full of things, but basically all the items have the same format :

TY223 [16]
TW121 [223]
...
...

If I want to substract the value 16 and TY223 from TY223 [16] , I go about it like this :

C#

string[] a = itm.Value.ToString().Split('[');
string[] b = a[1].ToString().Split(']');
string first = a[1].ToString().Trim();
string second = b[0].ToString().Trim();

This works fine, however I'm only after the value 16. Is there a more elegant way of extracting this value from the item, instead of using Split?

Kind regards,

[Corrected some code formatting]

Have you considered regular expressions?

Hi,

I like using regex:

System.Text.RegularExpressions.Regex r = new System.Text.RegularExpressions.Regex(@"[ [\]]");<br />label1.Text = "";<br />foreach (String s in r.Split(textBox2.Text))<br />{<br />  label1.Text += s + "\n";<br />}

You might use index 0 and 2 and you don't need .Trim() again. ;-)

Have fun

You might be able to do something like (I'd normally use something like this for reading from a file, but it seems to work here too):

string ReadWord(string buffer, char delimiter, int startPos)<br />{<br />    StringBuilder sb = new StringBuilder();<br />    for(int i=startPos; i<buffer.Length; i++)<br />    {<br />        if(buffer[i] == delimiter)<br />            break;<br /><br />        sb.append(buffer[i]);<br />    }<br /><br />    return sb.toString();<br />}<br /><br />void main()<br />{<br />    string firstPart = ReadWord(fullLine, ' ', 0);<br />    int startPos = fullLine.IndexOf('[');<br />    string secondPart = ReadWord(fullLine, ']', startPos);<br />}

Thats just from memory so it may not compile, but you get the idea.

How about this shorter one liner?

C#

string Result = inputString.Split('[')[1].Split(']')[0];

Solution 3

how about, in one line...

string resultString = inputString.Substring(inputString.IndexOf('[') + 1, inputString.IndexOf(']') - inputString.IndexOf('[') - 1);
